Since I've argued that the enforcement of antitrust law hasn't been strict enough many times in the past -- "the idea that markets 'self-police'" anti-competitive behavior always seemed much more of a hope than a reality in my view of the evidence -- to me this is good news (but it's not good news to everyone). It's not just the textbook economic effects of monopoly power that are worrisome, it's also the ability of large and powerful firms to tilt regulation and legislation in their favor:
Sherman Stirs: U.S. Revives Section 2 of the Antitrust Act, by Ashby Jones. WSJ: For nearly 120 years, the Sherman Antitrust Act has been the main vehicle through which the government and private parties have regulated the so-called anticompetitive behavior of corporate America.
The act's two main sections target vastly different types of behavior, though each may result in both civil liability and criminal punishment.
Section 1 largely addresses situations involving anticompetitive behavior of two or more entities working in concert. Cases involving price-fixing and market-division arrangements are typically brought under Section 1.
Section 2 cases typically involve the behavior of one firm, acting alone. Section 2 cases generally require a private party or the government -- either the Department of Justice or the Federal Trade Commission -- to show that a firm with a significant market share has done something anticompetitive in order to increase or maintain its monopoly. Monopolies, without evidence of anticompetitve behavior, aren't necessarily illegal.
While Section 1 cases are fairly common, the bulk of the headline-grabbing antitrust cases have been under Section 2... John D. Rockefeller's Standard Oil Co. ... AT&T... Microsoft ...
Enforcement of Section 2 went largely dormant under President George W. Bush. Toward the end of his second term, the administration issued a report which codified its views on Section 2. It took the position that the marketplace, not government regulators or courts, provides the ideal check on anticompetitive business practices.
In May, Christine Varney, President Barack Obama's pick to run the Justice Department's antitrust division, repudiated the Bush administration report, squarely placing some blame for the country's economic problems on the Bush administration's laissez-faire regulatory policies.
"Americans have seen firms given room to run with the idea that markets 'self-police' and that enforcement authorities should wait for the markets to 'self-correct,' " Ms. Varney said at the time. "Ineffective government regulation, ill-considered deregulatory measures and inadequate antitrust oversight contributed to the current conditions ... we cannot sit on the sidelines any longer."
Antitrust experts weren't surprised by Monday's news that with an initial review of conduct by large U.S. telecom companies [such as AT&T and Verizon], the Justice Department had started dusting off Section 2. ..
